This talk is part of the Triangle Computer Science Distinguished Lecturer Series
Abstract: Trio is a new type of database system that manages uncertainty and lineage of data as first-class concepts, along with the data itself. Uncertainty and lineage arise in a variety of data-intensive applications, including scientific and sensor data management, data cleaning and integration, and information extraction systems. This talk will survey our ongoing work in the Trio project: the new extended-relational "ULDB" model upon which the Trio system is based, Trio's SQL-based query language (TriQL) including formal and operational semantics, and a selection of new theoretical challenges and results. We will explain and demonstrate Trio's initial prototype implementation, and describe our planned research directions.
